题目内容

8.我不知道我们是否能够帮助跌倒的老人.
I don't knowif we can help the old people who fell down.(fall down)

分析 if we can help the old people who fell down.

解答 答案:if we can help the old people who fell down.这里是要表达出我们是否能够帮助跌倒的老人,是作为know的宾语从句,是说客观事实用一般现在时,引导词是if是否,主语是we,情态动词can后加动词原形help,后加宾语老人the old people,跌倒的老人,用定语从句,先行词是the old people指人,关系词用who做定语从句的主语,不可省略,跌倒用fall down的过去式fell down(已经跌倒用一般过去时),故答案是if we can help the old people who fell down.

点评 本题是两个从句的考查---宾语从句和定语从句,理解掌握其用法,可下多练习.
